My knowledge of 'FOD' comes from the Navy, in particular, aircraft carriers.
It is an acronym standing for 'Foreign Object Damage' or 'Foreign Object

On an aircraft carrier, there are periodic 'FOD patrols' whereby the crew
walk the flight deck, shoulder to shoulder, stern to bow and bow to stern,
to identify and remove any object that might get 'sucked up' into the intake
of a jet engine as aircraft are being launched.  A particularly bad time for
an engine failure and usually costs an aircraft and not uncommonly a crew.

OK, I'll bite, what does that one mean?

I'm pretty sure the keyboard isn't amenable to being opened without
permanent damage.
